You really do not want to look at or modify the general underlying code
of SetPropertyValue. This is a fundamental GUIKit framework function
for modifying any and all properties of all widgets in the entire
You are more specifically interested in the "expr" property of the
and so you want to look at the code that gets and sets this specific
As I have mentioned to you in previous personal correspondences, this
in the com.wolfram.guikit.graph.* classes
and in particular, the setExpr(Expr e) method on the class
This is where all of the construction of the nodes and edges of the
graph begin by reading the corresponding
Mathematica graph expression structure and this is where you would
begin to look at or modify how
the GraphEdit visual nodes and edges are constructed based on the
Mathematica expression being passed in.
